Due to a decline in demand for this product and the removal from production of the series 44 actuator by EAO, we are unfortunately unable to accept further orders for our HCP Series Pushbutton Switches.
The origin of the HCP goes back many years and it was designed to meet the requirements of the UK rail industry. At that time, the EAO Series 44 was in demand for drivers desks but the designers asked for a modification to replace EAO switching elements with Schaltbau types. This was achieved with the inclusion of a special interface bracket and the HCP Series was the result of this combination.
After EAO declared the discontinuation of the Series 44, we investigated the possibility of continuing with the suggested alternative from EAO. However the Series 45 is not interchangeable and the small, irregular demand makes it impractical to produce a new adaptor.
As we still have stock of certain piece parts, we advise existing users of the HCP Series to consider renovation in the short term rather than replacement.
Please contact us and we will see whether it is possible to renovate your switches using the parts available from our stock.
This new switch from Schaltbau enhances the features of the long-established S826 Series.
It’s polyetherimide case has a 50% higher impact resistance than the polyamide S826 and has an increased resistance to chemicals. The S926 can also be used at temperature extremes 20% to 30% better than the S826.
For applications such as industrial machinery, door controls and rail vehicle control panels, this switch gives the highest levels of safety and reliability.
This range of snap action switches is now available from Hertford Controls with strengthened mounting holes. Hollow brass inserts reinforce the mounting holes, preventing over-tightening of the switches during assembly.
This is a Hertford Controls initiative in response to customer feedback and is a far cheaper solution than specialised shoulder bolts.
It is important to note that the strengthened versions reduce the fixing bolt size from M4 to M3.
