SAFETY KEY SF 5 A

The SF 5A Safety Switch is a tilt safety switch with a vertical bracket and a weight mechanism that cuts off the circuit when tilted or tipped beyond 35°.

The SF 5A Safety Switch is a tilt safety switch designed to automatically cut off power if the device tips over or tilts beyond a specified angle. The switch body is mounted on a vertical bracket made of 0.8 mm thick sheet metal and 26 ±0.1 mm wide; the bracket’s 32.3 mm long upper arm ensures that the switch is positioned at a specific distance from the mounting surface. The Ø20 x 17 mm weight located beneath the bracket keeps the contact closed while the device is in an upright position; when the device tilts beyond 35°, the weight mechanism shifts position, opening the contact and breaking the circuit. The switch body has a base dimension of 35 x 16 mm, a height of 22.3 mm, and a depth of 23.2 mm; the total height, including the weight, is 42.5 mm.

Operating at a voltage of 240 V AC and with a current capacity of 16(4) A, the product is suitable for use with 16 A resistive and 4 A inductive loads. Thanks to its 125 °C (T125) temperature resistance, it can be safely installed inside the housings of heating devices. Connections are made via 6.3 x 0.8 mm tab terminals, enabling quick, tool-free wiring on mass production lines. With its On-Off (>35°) operating function, the SF 5A serves as a safety device in electric heaters, oil-filled radiators, fan heaters, and other portable household appliances at risk of tipping over. The long-arm vertical bracket design is suitable for applications where the switch must be mounted away from the device’s mounting surface.

The SF 5A Safety Switch, with a temperature resistance of 125 °C and a switching capacity of 16(4) A / 240 V AC, can be installed directly inside heating devices. Its mechanical design, which breaks the circuit when the device tilts beyond 35°, ensures that the device returns to a safe position without user intervention.

The product is designed and tested in accordance with the requirements of the relevant safety standards. It is capable of switching under a 16 A resistive / 4 A inductive load at 240 V AC, can operate at an ambient temperature of 125 °C (T125) ambient temperature, and an electrical cycle rating of 1E4; these features meet the safety criteria required for household appliances with heaters that pose a tip-over risk. The 6.3 x 0.8 mm tab terminal connection and perforated sheet metal bracket design provide repeatable and secure installation on mass production lines.
