High temperature resistance. Stainless steel even can work at temperatures up to 248?F(120C). The maximum pressure resistance of the stainless steel float can reach 30kg/cm2. Contacts are plated with rhodium, its life span can reach 2 million times. Switch liquid controller can be installed above or on side of the liquid level as required. ?HIGH SENSITIVITY?: Our ring magnet inside the float accurately controls the on and off of the reed switch. Sealing gasket can prevent water from leaking from the mounting hole. High temperature resistant wire copper plated with silver, surface braided layer insulation, high temperature resistant, prevent oxidation, greatly extending the service life. Connection part adopts waterproof solid glue, which has better waterproof performance and good sealing effectand to protect the safety of users! ?DIY CAN BE ADJUSTED?: Normally Closed (NC) and Normally Open (NO) can be adjusted manually, you need to use a vise to pull down the circlip under the float switch, Then adjust the direction of the float to realize the conversion between "NC" and "NO".
