    Latch does not work with transistor loaded

    I have a latch driving a transistor (indirectly through a few gates). The transistor is used to drive a relay that drives a 110V linear actuator motor. When the relay is not connected to the actuator motor, the latch works perfectly. A single button click is enough to set the latch, the reset...

    fast switch-off for transistor switch

    Hi guys, I have a simple transistor switch driving a relay. See the first figure (without diode D1). I have two such transistors driving two relays. The relays switch a 110V load. Ideally only one relay should be switched on at a time, so only one transistor should be switched on. The driving...
