XB7 Series Flat Head Buttons

Short Description:

LA37-E1. series push button switch = XB7 series push button switch + improved design.

(1) The contact is made of silver cadmium oxide (AgCdO15) material, which has high making and breaking ability and long life.
(2) The indicator light with the lighted button adopts LED light, which has low power consumption and long life.
(3) Two connection methods are available: screw connection method and Faston connector connection method.
Screw connection method: simple and convenient.
Faston connector wiring method: high connection reliability, especially suitable for use in places with severe vibration, such as: automobiles, lawn mowers, construction machinery, etc.
undefined EC2808-270
(4) It can be installed on the mounting plate with plate thickness = 10mm, which is the best among similar products.
(5) The integrated structure design is very convenient for installation, and at the same time, it can avoid product quality problems caused by improper installation.
(6) The knob switch and the key knob switch have the function of preventing following rotation, which can avoid the phenomenon that the body follows the handle rotation during use.
