The use and maintenance of the push button switches

The use and maintenance of the push button switches

(1)(Push button switch)Always check the button to remove dirt. Due to the small contact spacing of the button, after years of use or poor sealing, dust or oil emulsion will flow in, resulting in reduced insulation and even short circuit accidents. In this case, insulation and cleaning treatment must be carried out, and corresponding sealing measures must be taken.

(2) When the push button switch is used in high-temperature occasions, it is easy to deform and age the plastic, resulting in the loosening of the button and the collision and short circuit between the connecting screws. A fastening ring can be added during installation according to the situation, or an insulating plastic pipe can be added at the wiring screw to prevent loosening.

(3) The push button switchwith indicator light is easy to deform the plastic lampshade for a long time, which makes it difficult to replace the bulb. Therefore, it should not be used in places with long power on time; If you want to use it, you can appropriately reduce the bulb voltage and prolong its service life.

(4) If poor contact of the push button switch is found, the cause shall be found out: if the contact surface is damaged, it can be trimmed with a fine file; If there is dust or soot on the contact surface, wipe it with a clean cotton cloth dipped in solvent; If the contact spring fails, it shall be replaced; If the contact is seriously burned, the product shall be replaced.

The Construction Parameters of the Button Switch

The construction parameters of the button switchButton switch: an electrical appliance that turns on or off a small current circuit for a short time. It does not directly control the on and off of the main circuit, but sends out manual “commands” in the control circuit to control electrical appliances such as contactors, relays, and so […]

The basic concept of the push button switch(2)

Push button switch is a kind of electrical appliance that acts when pressed and resets when released, which is used to turn on and off small current circuits. It is generally used in the control circuit with AC / DC voltage below 440V and current less than 5A. Generally, it does not directly operate the main […]

Classification of Button Switches

Classification of button switchesButton switches can be classified according to operation mode and protection mode. Common button categories and characteristics:Open type: suitable for embedded installation and fixed on the panel of the switch board, control cabinet or console.Protective type: With a protective shell, it can prevent the internal button parts from being mechanically damaged or people touching […]
