Description These Micro Switches features Single Pole Double Throw (SPDT) Type, 1NO + 1NC Contact, Momentary Action, Hinge Roller Lever Actuator.Easy installation and long using life. Widely used in electronic equipments, Microwave Micro Door/Oven/Refrigerator Interlock N/O / N/C Switch etc.In snap action contacts, the movement of the actuator applies force to an overcenter mechanism. This mechanism creates a quick change in state when the trip point is reached. Reversing the motion of the actuator to a given reset point causes the contacts to snap back to their original position. Features - Color : Black, Red, Silver Tone.- Net Weight : 22g. - Overall Size(Pole not included) : 20 x 6 x 10mm / 0.8" x 0.2" x 0.4" (LWH).- Hinge Roller Lever Length : 18mm/0.7".- Roller Diameter : 4.5mm/0.2" Mounting Hole Dia. : 2mm / 0.08".- Mounting Hole Spacing : 9mm/ 0.35";Material : Plastic, Metal - Snap action contacts have different trip and reset points. The distance between the trip and reset point is called the travel to reset, hysteresis, or differential. Finite travel to reset helps to avoid multiple changes of state if the object actuating the switch is subject to vibration.- Snap action contacts ensure repeatable performance in applications that involve low actuators. The amount of travel of the contacts is also not dependent on the amount of travel by the actuator. Packing list: 1 * 10 Pcs Mini Micro Limit Switch Roller Lever Arm SPDT Snap Action LOT
