The 250V 15A (6s) ON-OFF black key switch with DOUBLE backlight is designed to switch AC electrical circuits with voltage up to 250V. Key (rocker) switches are used as components of various electrical equipment (in network filters and extension cords, audio equipment, power supplies, electrical installations in various industries and many other places). Such a key switch has two positions and two keys, which allows you to separately switch contact groups. The operating principle is based on moving the key to one of the positions. To switch to the desired position, you need to apply some force to the key. Installation is carried out without the use of screws on flat panels with a thickness of 0.8 mm to 3 mm. The contacts are connected using a 6.6 mm flat terminal or by soldering.
