Push Button Switches
When we say Push Button or Pushbutton Electronic Switches we are speaking of those types of switches found in or on electronic equipment such as power supplies, amplifiers, test equipment, etc. We stock Push Button Switches in Mini, Full size, 22mm Industrial, and more. Some Push Button Switches are lighted. The following are things you need to know about our Push Button Switches. These Switches can have a variety of Terminals (connections to switch) such as Screw, Solder, Quick connect, Printed Circuit Board and Wire leads. The Contact/Contact Set is the internal moving & fixed parts that open/close the circuit. The Actuator is the button in a Push Button Switch. Some basic definitions used are SP meaning Single Pole, 1 contact set for a single circuit, DP meaning Double Pole, 2 contact sets, for 2 circuits. 3P meaning 3Pole, 3 contact sets, etc. ST meaning Single Throw, the switch is closed or open, ON or OFF, 2 actuator positions shown as “ON/OFF”. DT meaning Double Throw, Switch has a common that alternates between 2 other contacts, 1 on, other off.
A Momentary Push Button Switch has the above actions except the stated contact function is maintained as long as actuator is pressed. When released, the button returns to the Rest position. A Push Button switches have two types; “Momentary” where the action only occurs when actuator is pressed; and “Alternate Action” where the contacts are maintained until pressed again. Push Button switches are available in Single & multiple Poles but are limited to two throws. The most common is the NO contact as in SPST-NO or DPST-NO. These are like a doorbell switch. The NC contact type is like the one found in your refrigerator light. Some of our industrial switchboard Push Button Switches are “Modular” where you can change the Contacts to form various combinations of NO & NC and are lighted.
