A switch device, comprising:
- a first switch including a first blade and a second blade, wherein the first switch is configured to be opened or closed based on contact or non-contact between the first blade and the second blade;
- a second switch including a third blade and a fourth blade, wherein the second switch is configured to be opened and closed based on contact or non-contact between the third blade and the fourth blade;
- a housing that accommodates the first switch and the second switch therein;
- and
- an actuator disposed in the housing and actuated to selectively open and close the first switch and the second switch, wherein the second blade is connected to a first conductor that passes through the housing, wherein the fourth blade is connected to a second conductor that passes through the housing, and wherein both the first blade and the third blade are connected to a common conductor that passes through the housing.
