Page 7: Connecting Devices Equipped With Reed Switches
Connecting devices equipped with Reed switches Reed switches are basically designed for small contact ratings. To connect a load with higher power consumption it is indispensable to use a contact protection relay (e.g. our series MSR01) If you connect directly a load to a Reed contact the following recommendations should be considered. - Page 8 Lamp Load Lamp loads consist e.g. by light bulbs, starting motors . WARNING: High current spikes at switching on, because the glowing spiral has low resistance at low temperature. Protective measures: (examples) Limitation of current by a resistor or preheating of the glowing spiral.
