Switches-category


A well known distributor of electrical components lists over 30 different types of switches in their catalog. We are not trying to be a general parts distributor. Instead, we offer a limited number of off-the-shelf products for sale on our web site. What these products have in common is they are often components of our custom products. We've taken the time to carefully select parts that meet our own standards so you can expect to find quality material listed in our catalog. We stock the following switch types:




Rocker

Rocker switches operate just as their name implies. Like a see-saw, they rock back and forth. Electrically, the number of switchable circuits is equal to the number of poles, and the switching positions are referred to as throws. So, a single pole single throw switch would control one circuit in an on/off fashion. In the off position there would be no connection. A double pole double throw switch could control two circuits connected to one set of contacts in one position and another set of contacts in the other - even if the other is not wired. Switching action is either maintained or momentary. In a maintained position, the switch stays put, so to speak. In a momentary position, it will spring back or return to a default position when you remove your finger. Common configurations include on/off (both positions imply maintained action), momentary on/off (spring return to off), momentary on/off/on (3 position switch with one momentary position and two maintained). You get the picture.

Toggle

Toggle switches have a handle that is moved back and forth from one position to another. Electrically, the number of switchable circuits is equal to the number of poles, and the switching positions are referred to as throws. So, a single pole single throw switch would control one circuit in an on/off fashion. In the off position there would be no connection. A double pole double throw switch could control two circuits connected to one set of contacts in one position and another set of contacts in the other - even if the other is not wired. Switching action is either maintained or momentary. In a maintained position, the switch stays put, so to speak. In a momentary position, it will spring back or return to a default position when you remove your finger. Common configurations include on/off (both positions imply maintained action), momentary on/off (spring return to off), momentary on/off/on (3 position switch with one momentary position and two maintained).

Rotary

Rotary switches are characterized by a knob and shaft. The poles of the switch are arranged in decks of multiple contacts that make and break depending on the angular position of the shaft.

Snap Action

Snap action switches are sometimes called limit switches. Intended to be operated by contact with parts of an assemble rather than by human hands, they are usually supplied in single pole double throw configurations.

Relay

Very simply, relays use an electromagnet to control a switch. The coil circuit (electromagnet) may be energized with AC or DC voltage, and the switch circuit may contain one or more poles. A single-throw relay is known as form A, while the double-throw type is form C. GAMA Electronics stocks only two types of relays - 40A and 80A, SPDT (single pole form C) with 12VDC or 24VDC coils. Common applications are winches, jacks, lifts and automotive controls. We have combined two of the 80A relays into a convenient polarity reversing configuration useful in many DC motor controls.
