Bistable relay BIS-403 BIS-403

Electronic bistable impulse relay allows you to switch on lighting or other device from several different points using control buttons connected in parallel. Action:
Short button press  closes the contact (switching on the connected receiver). The contact will be opened (turning off the controlled receiver) after the set time t has elapsed, or after pressing the button again.
Long pressing of the button, lasting at least 2 seconds, causes the contact to be permanently switched on. The contact will be opened only after pressing the button again  (or after power failure). The relay has no "memory" contact position, i.e. in the case of  power failure and its return, the relay contact will be switched off. Prevents  is automatic switching on of controlled receivers without supervision after a long-term power failure.
 BIS-403 cannot work with illuminated switches.
