7. Eltako Impulse switch
1 switch and 1 opener, potential-free, 16A/250V AC, suitable for 230V LED lamps up to 200W and incandescent lamps up to 2000W. No standby loss. Rail-mounted device for installation on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Either universal control voltage 12-230V UC at the control input +A1/-A2 or 230V with up to 5mA glow lamp current at the control input (L)/-A2(N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No continuous power supply required, hence no standby loss. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. By using a bistable relay, there is no coil loss and no heating even when switched on. The relay contact can be open or closed at startup and will synchronize during the first operation. The terminal connection layout is identical to the electromechanical pulse switch S12-110-. If this pulse switch is in a circuit monitored by a field disconnector, no additional base load is required. However, the monitoring voltage must be set to maximum. The electronics have no independent power supply and therefore consume no power in either contact position. Only during the brief control pulse of just 0.2 seconds does the control current flow, activating the microcontroller. It reads the last switching state from its non-volatile memory, switches the bistable relay accordingly in the opposite direction, and writes the new switching state back to memory.

8. Pilz 506308 PSEN ma1.4p-50/ 1switch
The PSEN ma1.4p-50/1switch is a magnetic safety switch designed for various applications in automation technology.
