Abstract
A tamper-detection switch is built into a device such as an encoder for a gas or water meter. The switch has a contact arm biased to complete an alarm circuit, but this is prevented by a restraining post. On installation, an actuator is moved by contact with the meter to lift the contact arm free of the restraining post, at the same time restraining the arm from completing the circuit. If the encoder is subsequently moved away from the meter, a biasing spring causes the actuator to move out of the path of the contact arm, freeing it to complete the alarm circuit.
