TENSE Bistable electronic impulse relay (Start-Stop / memory relay), 150-260 V AC

The bistable electronic impulse relay from TENSE (Turkey) allows you to control lighting or other devices from any location using push-buttons connected in parallel. It is ideally suited for households, commercial buildings, and industrial systems where simple impulse control is required without the use of conventional staircase or cross-bar switches.

Description and features

The relay allows you to switch a device on or off based on a short impulse from a momentary (bell) button. The internal bistable mechanism ensures that after pressing the button, the relay changes its state and maintains it until the next impulse. This provides simple and reliable control with one or more controllers in parallel.

A major advantage of this model is increased safety - the button input does not require a 220/230V mains voltage supply. A simple short circuit of the button contact is sufficient, which does not endanger the user and does not require the use of live wires at the control point.

Advantages and features

Safe operation without high voltage at the buttons
The control inputs operate solely on the principle of a closed circuit, eliminating the risk of electric shock.

Control from anywhere
Parallel connection for any number of buttons allows replacing cross and toggle switch systems and significantly simplifying wiring.

Saves wiring
Two-wire parallel button connection eliminates the need for complex switch combinations.

Compact size - 1 module
The relay does not take up much space and is easy to install in any home or industrial control panel.

Mounting on 35 mm DIN rail
Allows for standardized rapid assembly in distribution cabinets.
