A system comprising:
- a relay, the relay comprising:
- at least one contact;
- a reflector attached to at least one contact;
- a sensor, the sensor comprising:
- an emitter configured to emit a pulse;
- a detector configured to receive a portion of the emitted pulse;
- wherein the reflector is configured to reflect at least a portion of the emitted pulse received by the detector when the at least one contact is in at least one of:
- an open position and a closed position.
5 more elements
A method comprising:
- emitting, by an emitter of a sensor, a pulse;
- and receiving at least a portion of the emitted pulse through a window in a housing of a relay;
- wherein at least a portion of the emitted pulse is reflected by a reflector attached to a contact of the relay and received by a detector of the sensor when the reflector is disposed proximate the window in the housing of the relay.
