Switch

A switch comprising:

• a switch housing having a receiving space;
• a conductive fixed contact element and a conductive active contact element which are provided in the receiving space and being electrically connected to two terminals of the switch respectively;
• an actuating member reciprocating movable in a predetermined actuating direction between a rest position and an actuated position;
• and
• a conductive spring contact element movable with the actuating element, the spring contact element being in constant contact with the fixed contact element and switched between a state of being in contact with a conductive contact surface of the active contact element and a state of being disconnecting with the conductive contact surface of the active contact element, wherein the actuating element is moved back from the actuated position to the rest position due to spring force of the spring contact element;
• wherein a resistor is connected in series between the spring contact element and the fixed contact element or between the spring contact element and the active contact element, the resistor being correspondingly assembled on the fixed contact element or the active contact element.
