Abstract
A switch is provided. The switch includes, but not limited to: normally open (NO) terminals; normally closed (NC) terminals; an actuator, configured to conduct at least one of the NO terminals and the NC terminals; an indicator for a remaining service life of the switch; and a controller component, configured to: determine the remaining service life of the switch based on a conduct resistance between at least one of the NO terminals and the NC terminals, and control the indicator to illuminate a corresponding color based on the determined remaining service life of the switch.

A switch, comprising:
- normally open (NO) terminals;
- normally closed (NC) terminals;
- an actuator, configured to conduct at least one of the NO terminals and the NC terminals;
- an indicator for a remaining service life of the switch;
- and
- a controller component, configured to:
- determine the remaining service life of the switch based on a conduct resistance between at least one of the NO terminals and the NC terminals, and
- control the indicator to illuminate a corresponding color based on the determined remaining service life of the switch.
A switch, comprising:
- normally open (NO) terminals;
- normally closed (NC) terminals;
- an actuator, configured to conduct at least one of the NO terminals and the NC terminals;
- an indicator for a remaining service life of the switch;
- a sensor, configured to detect the actuator in an instance in which the actuator is pressed;
- and
- a controller component, configured to:
- determine the remaining service life of the switch based on times that the actuator is pressed, and
- control the indicator to illuminate a corresponding color based on the determined remaining service life of the switch.
A switch, comprising:
- normally open (NO) terminals;
- normally closed (NC) terminals;
- an actuator, configured to conduct at least one of the NO terminals and the NC terminals;
- an indicator for a remaining service life of the switch;
- a counting module, configured to count times that the actuator conducts the NO terminals;
- and
- a controller component, configured to:
