Ah, I can see the bent one is labelled COM and the other two are both labeled NO.
Either the switch is mis-labeled or one of those is an NC.
- A microswitch like yours won't have a spring-centered momentary push/pull like a "(on) off (on)" rocker switch.
When talking about switches, Common is
not the same thing as ground.
- In some countries the terms "common" and "ground" are used interchangably.
If you connect your wires to NO and NC they will never connect because the COM lever disconnects from NC before it connects with NO a.k.a. "break before make".
Here you can see what's happening inside the microswitch.
- Before you press the actuator, the spring holds the COM lever (green wire tab) against the NC (blue wire tab) contact.
- When you press the actuator, the COM lever tab makes contact with NO. (no wire tab)
