No. The datasheets I've read all say the same that you must activate the plunger straigt on. Any angle will give you bad performance. Any sideways stress on the plunger can kill the plunger assembly. The only alternative is to use a level-based micro-switch. That, however, will probably make it less accurate. Especially when you move over it side-ways. The angle of attack is too small with respect to the travel distance. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
