A slide switch includes a housing, two guiding slots, a slider, a push button, a first switch, a second switch, a third switch and two stopping blocks. Two middles of two inner surfaces of the housing protrude inward to form two supporting portions. A horizontal sliding path is formed among the two guiding slots and the two supporting portions. The slider is mounted between the two guiding slots. The push button is perpendicularly mounted to the slider. The first switch is positioned to one side of the sliding path. The second switch is positioned to the other side of the sliding path. The third switch is positioned to a center of the sliding path. The two stopping blocks are positioned at two opposite sides of the sliding path, respectively.

An electrical contact material may include a first contact that contacts a negative electrode; a third contact that contacts a positive electrode; and a second contact that is provided between the first contact and the third contact, wherein different plating materials are respectively attached to the first contact, the second contact, and the third contact.

A type of one-piece microswitch with built-in resistor(s) having a switch casing, a button on the switch casing, with a pedestal located in the casing, a common terminal, a first terminal and a second terminal installed for connection to external circuits with the common terminal electrically connected to the first contact, the first and the second terminals electrically connected to the second contact respectively. The common terminal is connected to the first and/or second terminal via one or more resistors with a switching device used for switchover of connection or disconnection between the first and the second contacts. The button and pedestal are connected by a spring piece or spring. The switching device is installed on the button, which constitutes a linkage with the button.
