2 switch control circuit
2 switch control circuit
(OP)
Hi,
I have a hydraulic system I am working on that uses 2 pressure switches to safeguard/lockout the units power switch. This is a 12v DC system where both pressure switches must be tripped to allow the unit to recieve power. The sensed pressure may fluctuate while operating the unit so the switch may open cutting power. To get around this I am considering wiring a SPST relay as a latching relay on each switch to hold the connection. These relays are followed by 2 more SPST relays in series to ensure both pressure switches are tripped. The units are operated for several hours at a time. Im conserned with the relays failing due to heat from energizing the coils continuously. Is there another way to do this?

Hey they have added 12VDC!(never mind about 24V)

Download the free software and see if you can get what you want working on the simulator.
