THE TRUE FORM B REED SWITCH — HOW’D WE DO THAT?
David didn’t invent the reed switch. But he spent 30 years perfecting it. Consider the True Form B Reed Switch. He’s engineered solutions for pacemakers, jumbo jets, and for products like submarines and the space station that push the boundaries of where we go and what we do next. No one else in the world has seen all he’s seen, and no one else loves putting that experience to work for you more than he does.
THE TRUE FORM B REED SWITCH
Recently the release of HSI SENSING’S HSR-376R — the world’s first true Form B reed switch — has been getting a lot of attention. And a lot of people have been asking how exactly it works and how it was developed. I’ll attempt to answer some of those questions here.
In the past, we, like other manufacturers, can and have offered a Form B switch by using 2 of the 3 leads used to make a Form C switch. Customers use the common lead and the normally closed lead, and ignore the normally open portion of the switch. This method of achieving a Form B function in a reed switch is not economical because you pay for a component in the switch that is unused.
What makes the HSR-376R different is that it does not have the 3rd switch lead — there is no Normally Open component inside the reed switch. The cost savings comes in not wasting that element.
Another unique thing about this switch is how it functions.
