Momentary Pushbutton Switch

The cutout 12.7mm pushbutton switch is a versatile and reliable component used in various electronic devices that require momentary switch operation. Its larger button head and snap-in mount make it easy to operate, while its technical specifications ensure efficient and safe electrical connections. Whether used in industrial control panels, automotive applications, or medical devices, this type of switch provides a simple yet essential functionality that contributes to the overall performance and safety of the equipment.

The cutout 12.7mm pushbutton switch features a larger button head than the 12mm momentary switch, which makes it easier to press and operate. The switch is also designed with a snap-in mount, where it snaps into the hole in the device’s front panel or printed circuit board. This type of switch is commonly used in industrial control instruments, automotive accessories, and medical equipment.

In terms of technical specifications, the cutout 12.7mm pushbutton switch typically has a maximum current rating of 3 amperes at 250 volts AC or DC. It has a minimum insulation resistance of 100 megohms and a minimum dielectric strength of 1000 volts AC for one minute. The switch is also rated for a maximum operating temperature of -25 to +70 degrees Celsius.

There are also different types of contacts used in pushbutton switches, including single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT). The SPST switch has only one pair of contacts, which are either open or closed. The SPDT switch has one common contact and two other contacts that can be connected depending on the position of the button. The DPDT switch has two common contacts and four other contacts, which can be connected in various combinations.
