Selector Switches（Shape：Circular Type）

The selector switch is a switch whose operation can be switched by turning the knob. The general mounting method of the selector switch is to make a mounting hole in the panel etc. and fix the switch body with the knob removed with the insertion ring. Press-fit the knob into it. Depending on the product, the diameter of the mounting hole is about ø10 to ø30, and some products require a square hole. The shape of the knob that comes out of the panel can be selected from round, square and rectangular. The number of notches is mostly about 2 to 5, the notch angle varies from 30 degrees to 90 degrees, and the operation method is divided into each position stop type and return type. The terminal shape can be selected from screw terminal, insertion terminal, solder terminal, etc. depending on the product.
