Staircase light time switches with a delay on release are operated by buttons that are often equipped with a glow lamp. The switch levers are designed for a glow lamp current of up to 150 mA and are therefore ideal for systems in multi-storey buildings. The staircase light time switch with a delay on release E 232-230 has an electromechanical time relay with a synchronous motor drive, which ensures a high level of operational reliability in any installation position. The time range can be set in 15-second increments from one to seven minutes. Can be switched on again after 30s. The multifunctional devices in the E 232E-230 Multi 10 and E 232E-8/230 Multi 10 product ranges have 10 functions that can be set on the front of the device.
