Surface Mount Test Switch KEY-S 10 Poles

The Konecty test switches were developed in accordance with the most rigorous safety standards in the electrical sector, designed to provide total safety to electrical panel operators.
Being the simplest, fastest, and most reliable method of performing tests, calibrations, and monitoring of electrical equipment, without the need to de-energize systems, they can test potential and current circuits of relays, energy meters, and other industrial applications.

Main cover with protection function during maintenance

It serves for protection when the test switch has open poles, that is, during maintenance, whereby the lower part of the switch, which is energized, is completely protected in case of impact or dropping of any tool or electricity-conducting object.

Test switch with cover in operation

Test switch with cover in maintenance

To use the KEY-S cover as protection for maintenance/testing, it is necessary that, with one or more poles open, the position of the cover is inverted, positioning the studs of the test switch in the lower holes of the cover and fixing with the closing nut, as per the example.

The poles will remain isolated and the operator will have the freedom to work on the contacts without danger.

Optional

Extended base for using three-phase socket for auxiliary equipment connection
Differentiated colors for keys
Phase identifiers on keys
Transparent cover with extended wings for protection of connection terminals
Interlocking pinn

Application and Operation

The KEY-S switches allow electrical isolation for connection, repair, or equipment monitoring when the blades are in the open position. In the closed position, the KEY-S maintains the operation and continuity of electrical circuits within their normal characteristics.

Constructive Characteristics

Base

Injection molded in plastic material with excellent insulation and mechanical resistance, capable of withstanding high temperatures without deforming its structure.
Can be provided in the following versions:

Base injection molded in black or crystal clear polycarbonate;
Basic with or without lateral fixing wings;
Extended black base for use with three-phase socket for connecting similar equipment.

Main Cover

Injection molded in transparent plastic material with high resistance against mechanical shocks. The cover is removable and features sealing devices against fraud. Designed to protect connection terminals and provide more agility to the operator, it comes in versions with extended protective wings, without protective wings, and with cut-out protective wings for wide conductor passage. Features an indelible identification with information about the manufacturer, product, model, year of manufacture, voltage, and current.

Voltage and Current Disconnection Sets

All disconnection sets are manufactured in special extra-hard brass, with spring effect and surface protection treatment of components. They have excellent mechanical resistance and electrical conductivity.
The voltage disconnection sets consist of simple blade switches with independent activation for potential circuits. They are separated by insulating barriers molded into the base and with reinforced height to prevent any possibility of voltage arcs.
The current disconnection sets are composed of blade switches that allow short-circuiting the secondary of current transformers before the total opening of the blades. Along with these disconnectors, there is a measuring bridge for each current circuit, allowing the use of auxiliary equipment without the need to disconnect conductors.

Neutral Pole

Consists of a continuous key or blade manufactured in special extra-hard brass, connecting the input and output terminals of the switch.

Blade Actuation Keys

Injection molded in high-resistance insulating plastic material to protect the operator from touching conductive parts. They are designed with an ergonomic opening and can be configured with differentiated colors, circuit identifiers, and mechanical interlock pins to open two blades simultaneously.

Connection Terminals

Produced in brass with surface treatment and excellent electrical conductivity, allowing a firm and secure connection of conductors.

Assembly and Connection

The KEY-S switches are mounted frontally on panels and measurement sets.

Their installation is designed to provide safety and practicality for operators. Fixing is done through four M5 screws located, after installation completion, inside the main cover with a security seal against fraud.

Conductor fixation is made in M5 terminals, which can also be done using ring-type connectors (minimum internal diameter of 4.2mm and maximum external diameter of 11.5mm) or directly through stripped conductors using nail-type conductor fixing plates existing in the KEY-S connection terminals.

Tightening of connection terminals can be done using a conventional screwdriver or even using 5/16″ hexagonal “pipe” wrenches. The KEY-S connection terminals also allow the use of “banana” plugs, thus obtaining greater flexibility according to operators’ needs.
