TE Connectvity’s Economy Power wire-to-board connectors

TE_connectors copy

TE Connectvity’s (TE) Economy Power (EP) wire-to-board connector family is widely used for power circuit applications. Based on the proven EP version the new and advanced EP II and EP 2.5 lines offer additional benefits. EP II connectors are rated for 600VAC at up to 11A making them a fit for a larger range of applications. Their electric properties also make them an option to mix signal and power in one connector. Additionally, the compact EP 2.5 family is based on a .098″ [2.5mm] pitch and is rated for 250VAC at up to an industry-leading 4.5A. With a 26 to 20 AWG [.121-.601 mm²] wire size, and up to 20-positions, EP 2.5 is suited for board power delivery when space is at a premium.

Both EP II and EP 2.5 connectors offer two levels of mechanical and electrical reliability: A true locking latch prevents the plug housing and post header from vibrating apart, while an optional Terminal Position Assurance (TPA) device helps assure terminal seating.

Potential Applications:

  • Coin changers/vending machines
  • Commercial & building equipment
  • Generators
  • Household appliances
  • HVAC & vending controls
  • Industrial machinery & equipment:
  • Lighting

Carling Rocker Switches: Dependable Devices for Accessing Power

As an electrical component distributer that is franchised for roughly 60 leading manufacturers, Gopher Electronics is able to offer your company a wide range of electrical parts and accessories including rocker switches and rocker switch accessories. When it comes to turning on a power source for a variety of electronic devices and accessories, it is as simple as flipping a switch. We understand the importance of having a reliable switch for these devices, so we provide our customers with a variety rocker switches, including Carling rocker switches and accessories, to ensure you are not left in the dark.

Reliable Power from Carling Rocker Switches

A rocker switch is an on/off switch that rocks when pressed, where one side of the switch is raised while the other side is depressed, making it rock back and forth as the switch is turned on and off. One side of the switch usually has a circle for “on” and a horizontal dash for “off” to indicate if the switch is on or off. Rocker switches are commonly used in surge protectors, computer power supplies, display monitors, as well as many other applications.

At Gopher Electronics we work with some of the leading manufacturers in the world, like Carling Technologies, to provide you with reliable parts including but not limited to switches, sensors, and circuit breakers as well as connectors, cords, and fuses, to ensure you have the proper parts to get the job done. Our stock of rocker switches includes a wide variety of products to meet your needs.

Rocker Switches to Match Your Application

Carling rocker switches are available in miniature switches ranging from .4VA to 20 amp, illuminated and non-illuminated and double insulated in single or double pole configurations. Full-sized switches are also available ranging from 3 to 20 amp, illuminated and non-illuminated, in one to four pole configurations. The full-size switches we carry are available with nylon snap-in or screw type mounting brackets and are AC rated and can be used for lower voltage DC applications.

Sealed rocker switches are also available, to prevent damage from dust, spray, pressure or constant immersion for use in the marine industry or other places where damage to a switch could occur.
